I'd suggest using the paper file pages which are available. These allow the negative strips to 'breathe' far more than the plastic sleeves. The paper may well be less protective than the plastic in the long term (many decades), but I have been using both sorts of sleeves for nearly forty years without noticeable problems - I have lived only in an easy climate though.
The gelatine and emulsion coating of the plastic film will have the same moisture content as it's surroundings, however if the humidity is very high then the film may not dry out enough to withstand repeated handling. If this seems to be the case in future then it will be worth looking at using a hardening-fixer to toughen the emulsion chemically. This is a perfectly legitimate way to cope with climatic conditions and the only (slight) downsides are a few more minutes fixing and washing time.

If you do have access to somewhere that has humidity control, that would be the place to finish drying the negatives and sleeving them.
“Photography is a complex and fluid medium, and its many factors are not applied in simple sequence. Rather, the process may be likened to the art of the juggler in keeping many balls in the air at one time!”
Ansel Adams, from the introduction to The Negative - The New Ansel Adams Photography Series / Book 2
I had a similar experience when I accidently mixed photo-flo at 1:20 instead of 1:200. There was sticky soap on the negs! After watching the plastic sleeves scratch some c-41 negs, I stopped using them altogether. I put my negs in envelopes between slips of acid free paper.
I'd suggest OP to dry it overnight and try this again.
I live in HUMID Florida and have not experienced this. Of course my house is air conditioned and OP lives in India, so that may be a factor. I understand electrical service is not that reliable and A/C is not commonly in use in many parts of the country.
Well, seeing as you live in Mumbai and it is summer there, the best thing you could probably do is get a hairdryer and use that. Even in Florida the humidity isn't 100% which is what you may be experiencing. If the humidity is close to 100% the negs just won't dry without a little help.
